EJB 2.1 & J2EE 1.4 IIRC

Why don't we start different threads for different issues?
This thread start out as discussing making management easier.
e.g. Joe Windows Admin wants a GUI Wizard entitled
"Configure datasource" preferably one that does not ask if he writing
letter :-)
How does Joe hates-GUIs programmer (i.e. me) maintain that wizard
and other management interfaces when I add configuration options
to the jdbc rars or db specifc plugins?
The datasource is a good/pathological example because it also includes
"advanced" configurations like the CMP mappings,
jbossmq persistence config and the pad=true xid for Oracle.
Showing disparate metadata needs to be combined in the management
view/tool.
But this is exactly the use-case for a xsd-xslt. JBoss.org is providing 
a wholesale XML based on a wholesale XSD and joe average is xslt'ing it 
to fit his needs. Or bax is able to customize the 
build-test-deploy-configure cycle for his client without 
trial-and-error-sometime-look-into-the-source crap.

Why not generating the gui out of the xsd? Why not using the jdbc 
metadata for datasource config by changing the appropriate xml schema 
description, naturally on the fly at invocation time? What about a 
metadata interceptor? ;-)
Same content - different semantics.

Scott's posted some of the requirements in the past, e.g.

Decoupling of all content (class instances) from all semantics

One of the key issues is supporting the old deployments,
by translating them into the "new" object model.


jaxb doesn't cut it, it has limited/no support for changing schemas
or an already established object model.
The XSD is the Object Model regardless of the content of the referenced 
XML, so one may apply different XSD on the same XML - or even on the 
XSD's. Ok, at last you may generate the .java's :)))

The answer is: You are applying different semantics on the same XML

Re: [JBoss-dev] Re: [Core] WG: Comparison between BEA & JBoss

2003-11-05 Thread Holger Baxmann @ mac
The problem is not writing the right code or using the right OM. The 
problem is applying the right code with a appropriate OM at the right 
time to the right understanding, taxonomy and onthology of the USER.

Code doesn't sell, the "right" functionalities at the "right" times 
will sell.

Today we are generally not able to fullfill this need. Sometime we come 
closer, sometime we fail. If we come closer, the USER will change his 
mind - we will fail. ;-)

The issue is _not_ the data, it is the MEANING.

We are trying to seperate the the ontologies into interface, the 
taxonomies into interceptor and invoker. All these are stateless in the 
case of content. Go one step further and decouple the meta-data and hot 
deploy them.

Continous Build&Test on the metadata. Including Refactoring of 
metadata. At runtime.

There are some good examples for this: look for "XML Schmema ontology" 
in google or applying the MOF to JBoss.org.
ebXML and RosettaNet, in case of already defined Schema 
implementations, would be helpfull to be transformed by XSLT into a 
JBoss DD.

And, again: You can generate the whole code out of XSD meta and XML 
content in a standard way, but not vice versa.
Java code is only a special case of formulating MEANING, it is ugly in 
this. XSD is make for describe MEANING.

For example MEANING of an applied security model.
Ok, it is regarding the level of the USER of JBoss, not the level of 
the coder of JBoss.
Sorry for beeing one of the first.

Am 05.11.2003 um 04:18 schrieb Scott M Stark:

Explain how xsd is actually the object model in terms of what
the metadata handling code is using. Its directly manipulating
xml instances that conform to the xsd or is there is a binding of
the xsd to a java object model? If there is a binding, then that
is the object model, not the xsd as that is what the code is
dependent on. Why would I want to directly use some xml api and
propagate around dependencies on xml parsing (which we already
do to much of), rather than handling one particular externalized
form of the metadata and then passing the object model around?

Re: [JBoss-dev] 4.0 Roadmap

2003-11-14 Thread Holger Baxmann @ mac
hi adrian,

I am also interested in working in the JACC area.

I propose this roadmap:


0) Make JBoss with run with a security manager config that does not
assign all authority to all classes!
.. and i thought i was a lonely caller in the wild, or rather a catcher 
in the rye :-))

thumbs up

bax

Regards,
Adrian
1) implementing the required javax.security.jacc.* classes/interfaces 
in
j2ee module.
this javax.security.jacc.* does not depend on jboss

2) implementing a MBean that manage jacc

3) [the dirty work] rewrite/restyle the jboss security system :-)

For point 3, I have in mind this proposal:

- we need j2sdk 1.4 then we can remove deprecated classes

- jaas authentication with 
javax.security.auth.conf.AppConfigurationEntry[]
associated to single module (ejb, ejbjar, ear, web, sar etc) with 
default to
parent module.
  in this way a ejb is self contained and we don't need to modify the 
global
configuration

- jaas authorization associated to single module with merging to 
parent
module (so we can run ejb/sar & co in a sandbox)

So, I wrote a very simple frame that reads xml files and constructs

ejb-jar.xml and then populated with other data from jboss.xml and  
jbosscmp-jdbc.xml.

But I would like to use something common, i.e. server-wide solution

Re: [JBoss-dev] metadata management

2003-11-15 Thread Holger Baxmann @ mac
mmmhm, RelaxNG is a superset for XML Schema. It could be handled W3C  
Schema compliant and could generate standardized XSD from its own  
Schema. AFAIR via XSLT.

I would suggest it because of the comfortable, easy and short way to  
_get_grip_. I know of no other XML Application which could go from DTD  
to XSD in such an easy manner.

Forget about the funny basic-like own language in RelaxNG.

RelaxNG and W3C XML Schema are not distinct they complement each other.

from my experience with schema, XML W3C schema are a big mess,they are

cool.
But schema are widely accepted (microsost push) and recognized by the

I am facing it right now. I would like to have, say, entity metadata
from various sources (ejb-jar.xml, jbossxmp-jdbc.xml) in one place.
So, I wrote a very simple frame that reads xml files and constructs
the metadata tree. Actually, the metadata tree is built while  
reading
ejb-jar.xml and then populated with other data from jboss.xml and
jbosscmp-jdbc.xml.

But I would like to use something common, i.e. server-wide solution
if we are going to agree on it.
